More megapixels generally equal more detail in your photos. They definitely mean more storage is required to hold each shot. The Lexar Professional 1TB SDXC Memory Card was built with this in mind. It offers write speeds of up to 70MB/s and reads up to 95MB/s, making it ideal for 4K video work as well as high-res stills. Class 10 certified, it also makes for quick transfers when the shoot is over and editing begins.
